[vbox-dev] Network restoration after snapshot

Jaikumar,

This behavior is intentional. Machine's state may be saved in one network environment, and restored in completely different one (VM on laptop that brought home from office, for example). VirtualBox forces the link down and back up after a timeout.

Regards,
Aleksey
